O A. (x-3)2 + (y-2)2 = 25
B. (x+3)2 + (y + 2)2 = 5
C. (x2 - 3) + (12 - 2) = 52
O D. (x - 2)2 + (y - 3)2 = 25

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
